The time course of negative repetition effects in post-cue naming

It has previously been shown that when picture pairs are repeated across blocks in a post-cue naming task, former distractors are named faster than former targets: the “negative repetition effect” (Mayall, Humphreys, & Kotsanis, 2002). In the present study the time course of this effect was examined. Experiment 1 demonstrated that the effect became apparent after a lag of only two intervening trials, with former targets being named faster than former distractors after a lag of zero trials. Experiment 2 used a new baseline condition with repeated picture pairs for which no response was required on the first presentation. Comparisons with this baseline indicated that the negative repetition effect is the result of suppression of former targets as opposed to facilitation of former distractors. The results support the proposal of Mayall et al. that the negative repetition effect reflects a form of speech monitoring that is applied when there is competition in the process of mapping from semantics to name representations.     

Navigating the spaces of children’s spiritual experiences: influences of tradition(s), multidisciplinarity and perceptions

ABSTRACT

Children across the world report similar spiritual experiences. Empirical studies suggest that most resonate with the children’s traditions; a finding which should, in theory, afford them a safe spiritual space. However, a number of factors can situate them in a less certain place. The paper uses the metaphors of trees imbued with different shades of light, from the vivid, shimmering and opaque to the invisible, to illustrate the types of spiritual spaces in which children find themselves. Their location is shaped in part by connection or disconnection with traditions, alongside wider cultural forces. Three navigation tools are used to show how children may move between these spaces: the spiritual experience and its relationship with traditions; the influences of multidisciplinary approaches; and children’s perceptions of their experiences. The paper concludes that these metaphors and tools may be a useful way to understand the spiritual spaces in which children find themselves.     

A story superiority effect for disgust,fear, embarrassment,and pride

Past studies found that, for preschoolers, a story specifying a situational cause and behavioural consequence is a better cue to fear and disgust than is the facial expression of those two emotions, but the facial expressions used were static. Two studies (Study 1: N = 68, 36–68 months; Study 2: N = 72, 49–90 months) tested whether this effect could be reversed when the expressions were dynamic and included facial, postural, and vocal cues. Children freely labelled emotions in three conditions: story, still face, and dynamic expression. Story remained a better cue than still face or dynamic expression for fear and disgust and also for the later emerging emotions of embarrassment and pride.     

Attention in Williams syndrome and Down's syndrome: Performance on the new early childhood attention battery

Attentional problems are commonly reported as a feature of the behavioural profile in both Williams syndrome (WS) and Down's syndrome (DS). Recent studies have begun to investigate these impairments empirically, acknowledging the need for an approach that considers cross‐syndrome comparisons and developmental changes across the different component functions of attention. The present study assessed children with WS and DS using a new preschool attention battery (ECAB: early childhood attention battery), designed to be suitable for mental age 3–6 years including groups with developmental disorders. The ECAB has the advantage of giving an individual profile of attentional abilities for each child, covering different components of attention. In relation to test norms for their mental age, both groups showed a profile of strengths and weaknesses in the attention domain. Both syndrome groups performed relatively well on tests of sustained attention and poorly on aspects of selective attention and attentional control (executive function). The DS group showed a specific strength in auditory sustained attention, whilst the WS group showed a particular deficit in visuo‐spatial response control. There was also evidence for considerable differences in the developmental trajectory of these abilities across the two groups. The results provide evidence for syndrome‐specific patterns of impairment, and distinct profiles of strengths and weaknesses that may be useful in understanding the nature of everyday attention difficulties in these groups and tailoring interventions to meet these needs.
